COLLAPBIBLE TUBE WITH AN UNLOSABLE CAP.

Application illed July 5,

My invention' relates to a collapsible tube with an unlosable cap, andmore particularly .'to such a tube or container having a screwcap whichis ordinarily removed to permit discharge of lthe contents from saidtube. Such removed caps'are frequently dropped or misplaced and lost;and itI is my object to provide such a tube with a cap which is movablebut not removable or losable therefrom; and a further object is toprovide such al cap with means for mounting it unlosably on the tube, bythe use of a minimum of parts and thereby provide a very economicalconstruction.

Other objects will appear hereinafter.

The invention consists in the combinations and arrangements of partshereinafter described and claimed.

The invention will be best understood by reference to the accompanyingdrawings forming a part of this specification, and in which,

Fig. 1 is a side elevation ofv my invention;

Fig. 2 is a view partly in section taken on line 2-2 of Fig. 1;

Fig. 3 is a partial view showing the cap in closed positlon; and

Fig. 4 is a view of the caplwith its locking lug bent laterally beforemounting said cap on theI tube.

`The form of invention illustrated comprises a collapsible tube orcontainer 10 generally used for holding and dispensingshaving cream,face cream, tooth paste, etc., and which is provided with a threadedneck 11 and an annular should-er 12 at the lower end of said neck, adischarge channel or passage 13 extending longitudinally through saidneck, and a discharge opening 14 extending through said necktransversely from said channel 13. A cap or closure member 15 isprovided with an interior thread'ed passage 16 to fit the threads onneck 11, and an opening 17 is provided in the side of said cap adaptedto be registered with the opening 14 1n the neck 12.

The means for positively retaining the cap on` the neck includes al lugor projectlon 18 being integral with and extending downwardly from cap15, and a lug 19 provided on neck 11 and extending upwardly -from theannular shoulder 12.

For the purpose of assembling the device, lug 19 may be fastened on neck11 andannular shoulder 12 after the cap ,15 has been 1924. Serial No.724,274.

threaded entirely downward on neck 11, and this lug 19 is then placed inposition so that the side openings 14 and 17 are in register when thecap 15 is turned or rotated upwardly so that its lug 18 engages the lug19, as indicated in Figs. 1 and 2. A slight rotation, about a quarterturn, in clockwise direction will bring lug 18 down on annular shoulder12 and stop the downward movement of the cap and at the same timecompletely close the opening 14 on the neck. Or if it is desired the lug19 maybe made integral with annular shoulder 12 and neck 11, in themanufacture of the tube, and-the lug 18 on cap 15 may be bent outwardlyas shown in full lines in Fig. 4, and the cap then threaded in positionon the neck, and when the cap has been moved downwardly into theposition shown in Fig. 3 then lug .18 may be bent downwardly into theposition shown in dotted lines in Fig. 4 and as shown in full lines inthe rcmaining figures, thus providing locking means on the cap and tubefor preventing the removal or loss of cap 15 from tube 10. My devicethus includes a. minimum of parts. namely two integral parts, whichmakes it ver)7 economical in manufacture.

While I have illustrated and described the preferred form ofconstruction for carrying my invention into effect, this is capable ofvariation and modification without departing from thespirit of theinvention. I, therefore, do not wish to be limited to the precisedetails of construction set forth, but desire to avail myself of suchvariations and modifications as come within the scope of the appendedclaims. v

Having described my inventionA what I claim as new and desire to secureby Letters Patent is: c

1. A collapsible tube having an annular shoulder and a threaded neckextending upwardly therefrom provided with a. longitudinal passage andcommunicating with the inte-rior of the tube, the neck also having a.discharge opening extending transversely from said passage, a lug`formed integral with the shoulder, a cap provided with a dischargeopening in one side and registerable with the transverse opening, and alug formed integral on the lower edge of the cap and being bendabledownwardly and inwardly to engage the first lug` and stop removalof thecap when the openings are locK in registration, the lug on the capengaging the annular shoulder to limit the movement of the cap forclosing said openings.

2. Acollapsible tube having a threaded neck and a cap threaded thereon,a stop carried by the tube at one side of the neck, and a bendable lugcarried by the cap and arranged to be disposed to clear the stop topermit the cap to be rotated freely or to eX- tend in the path ot' thestop whereby the rotation of the cap is limited.

3. The combination with a collapsible tube having a discharge opening inone side of the neck thereof and a cap threaded on 15 the neck and alsoprovided with an open- `side of the neck, and a bendable lug carried bythe cap normally arranged at right 20 angles to the latter to permit theca to be threaded -on the neck and subsequent y bent to occupy aposition Where :it will enga the stop upon rotation of the cap to on yallow the cap to be rotated suiiiciently t0 bring its outlet openinginto registration with the outlet opening in the neck.

In testimony whereof I have signed my name to this specifica-tion.

GEORGE E. BAKER.
